IMPROVEM ENT IN GLOBE-VALVES.

Specification forming part of Letters Patent No. 123,8-48, datedFebruary 2 0, 187:2.

To all whom it may concern:

Be it known that I, ELI THAYER, of Worcester, in the State ot'Massachusetts, have inl venteda new and useful Improvementin Globe-Valves for discharging or conducting uids from reservoirs and forregulating` or graduating the ilow ot' the same and that the followingis a true and accurate description thereof, reference being had to theaccompanying drawing forming a part of this specitieation, in which-Figure l represents a perspective view; Fig. 2, a vertical section ofthe same Fig. 3, asection transversely through the center.

The invention consists in constructing the valve-cock or faucet in twoSections, the lower one provided with and carrying the valve so that theopening and closing and regulating ot' the iiow ot' the fluids aresecured by turning the lower section in the direction required for thepurpose.

A and B, Fig. 2, represent two sections of hollow cylinders or pipes.The upper end of A is provided with screw-threads d, or other suitabledevice to secure it to the supply-pipe reservoir or other receptacle ofthe liuid, and its lower part with Screw-threads b to work easily incorresponding threads in section B. rlhese screw-threads may be of anysize or pitch desired to facilitate the movement of section B in openingand closing the valve. The

lower end should have sufficient surface to secure a close connectionwith thevalVe without cutting or abrading it. The opening in section Bat and below the valve c must be larger than in A, so as to permit aneasy discharge ot' the tluid, and prevent a rebound or backward pressurethrough the screw-threads unitin g the two sections A and B. The wholeSection B may be so enlarged as to allow the arms a a and the valve ctobe put into position from below; but the better construction is a hollowglobe containing the valve, as shown in the drawing.

For economy in manufacture the globe should be either spherical orspheroidal, though with greater c oSt it maybe made square or polygonal.The valve c is secured to the arms at their junction by the pin p.

This valve may be made of rubber, leather, Soft metal, or other suitablematerial, and should have beneath it a metallic washer to revolve on thearms a a', so as to prevent its wearing or abrasion in opening andclosin What I claim as my invention, and desire to Secure by LettersPatent, is-

rlhe movable globe or section B, carrying the Valve c, substantially asset forth.
